It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that it was asked from the Prophet (peace and blessings of Allah be upon him): Which deeds are the best? He (peace be upon him) said: "To have faith in Allah and to strive in His path." The questioner said: Which slave is best to set free? He (peace be upon him) said: "The one who is the most valuable and the best in the eyes of his owners." The questioner said: If I am not able to do some deeds, then what do you think I should do? He (peace be upon him) said: "You should help someone who is helpless, or do the work of someone who is incapable." The questioner said: If I am unable to do even this? He (peace be upon him) said: "Then refrain from harming people, for this too is a charity that you give to yourself."
